The HP 48GX got me through from high school college prep to EE/CS. I also happen to own an HP 48 overhead projector display and a thermal printer. Now, I just need an overhead projector to even use (the former). Sharing software was the killer app of the HP 48 G series, and the app that turned the serial IR port into a universal learning remote was a pranksters' dream because the IR LED was so overpowered.
